The results showed that the rumen NH3-N concentrations of the animals in A3 and B1 treatments were decreased signi.

[Method] The NH3 concentration of the vertical direction at different locations and horizontal direction at different heights in chicken house under the open and closed states of the fan were tested,and the changes of sentinel surveilance NH3 concentration depended on the variation.

The main pollution factors chemical oxygen consumption(COD)and ammoniacal nitrogen(NH_3-N)of the experiment water are analyzed according to the National Standard Analysis Method after studying the treatment effectiveness influenced by the environment factors and the technology reference data.

Based on the analysis of variation of NH_3-N,phosphorus and organic compounds in soil samples from bottom mud and penetration media of river bed,it is found out that bottom mud has great effects on removal of NH_3-N and phosphorus,the amounts of which in mud are over ten times and one time as high as those in penetration media,respectively.

Methods The high effective complex microorganisms were domesticated to treat the leachate and the Chemical Oxygen Demand(COD_(Cr)) and NH_3-N were detected.
